We present Cassini VIMS observations of sun glitter -- wave-induced reflections from a liquid surface offset from a specular point -- on Kraken Mare. Sun glitter reveals rough sea surfaces around Kraken Mare, namely the coasts and narrow straits. The sun glitter observations indicate wave activity driven by the winds and tidal currents in Kraken Mare during northern summer. T104 Cassini VIMS observations show three sun glitter features in Bayta Fretum indicative of variegated wave fields. We… 


Cassini/VIMS observes rough surfaces on Titan’s Punga Mare in specular reflection
Cassini/VIMS high-phase specular observations of Titan’s north pole during the T85 flyby show evidence for isolated patches of rough liquid surface within the boundaries of the sea Punga Mare, which would represent the first waves seen on Titan's seas, and also the first extraterrestrial sea-surface waves in general.
Winds and tides of Ligeia Mare, with application to the drift of the proposed time TiME (Titan Mare Explorer) capsule
Abstract We use two independent General Circulation Models (GCMs) to estimate surface winds at Titan’s Ligeia Mare (78° N, 250° W), motivated by a proposed mission to land a floating capsule in this
A radar map of Titan Seas: Tidal dissipation and ocean mixing through the throat of Kraken
Abstract We present a radar map of the Titan’s seas, with bathymetry estimated as proportional to distance from the nearest shore. This naive analytic bathymetry, scaled to a recent radar sounding of
Wave constraints for Titan's Jingpo Lacus and Kraken Mare from VIMS specular reflection lightcurves
Abstract Stephan et al. (Stephan, K. et al. [2010]. Geophys. Res. Lett. 37, 7104–+.) first saw the glint of sunlight specularly reflected off of Titan’s lakes. We develop a quantitative model for
Surface of Ligeia Mare, Titan, from Cassini altimeter and radiometer analysis
Cassini radar observations of the surface of Ligeia Mare collected during the 23 May 2013 (T91) Cassini fly-by show that it is extremely smooth, likely to be mostly methane in composition, and
Numerical simulation of tides and oceanic angular momentum of Titan’s hydrocarbon seas
Abstract Tides and tidal currents in Titan’s hydrocarbon seas are numerically simulated by a 3-dimensional ocean circulation model using a bathymetry map constrained by Cassini. These predictions are
Wind driven capillary-gravity waves on Titan’s lakes: Hard to detect or non-existent?
Saturn’s moon Titan has lakes and seas of liquid hydrocarbon and a dense atmosphere, an environment conducive to generating wind waves. Cassini observations thus far, however, show no indication of
Simulation of tides in hydrocarbon lakes on Saturn’s moon Titan
Numerous hydrocarbon lakes have recently been detected on Saturn’s largest moon Titan, representing the only known large bodies of liquids on a planetary surface outside the Earth. In the context of
Wind-driven surface waves on Titan
The surface of Titan represents the largest surface area in the solar system essentially unexplored, although recent observations from Hubble Space Telescope and ground-based telescopes using
Currents through Torres Strait
Abstract A five-month field study of the circulation in the Torres Strait was carried out. Baroclinic effects were negligible. The Arafura Sea and the Coral Sea forced a different tide on either side
